The Basics of Special Relativity Remain Unchanged: It is Merely a Conceptual Modification of the Mass– Energy Equivalence Equation
Einstein proposed the land marking special theory of relativity for the first time in 1905. Few understood it at the time, and even fewer believed in it. It wasn’t until 1919 that the first experiment on the general theory of relativity was carried out, which actually proved the special theory of relativity by some of the experiment’s inferences. The mass – energy equivalence equation will be revised in this chapter with some conceptual changes in light of particle – antiparticle pair production and annihilation. The fundamentals of special relativity theory remain unchanged, but the conceptual framework has changed. The changes are arranged to support the conclusion. In physics and astronomy, 1905 was a watershed moment when Einstein proposed the special theory of relativity for the first time. This theory serves as the basis for modern astronomy and astrophysics. This theory also served as the foundation for Einstein’s general theory of relativity, which he proposed in 1915 to incorporate gravity into the system. Thus, since the early nineteenth century, the special theory of relativity has been of supreme importance in physics, and it continues to be the right from the start theory in modern physics. This chapter attempts a deliberate and comprehensive derivation from a special theory of relativity equation. The derivation is made with the goal of delving deep into the theory of special relativity in order to reach a comprehensive conclusion. Some conceptual changes are also arranged to support the conclusion. Some equations in this chapter relate physical time, mass, and velocity.
